UTOPIA support for MPC885 with 2.6.15 kernel

UTOPIA support for MPC885 with 2.6.15 kernel

[Pelton, Dave]

Hello,

I am currently working with a MPC885ADS board running a 2.6.15 kernel
build.  I have been attempting to get the UTOPIA interface working, but
I have not been able to find kernel code (or patches) to do this. =20

The closest I have found so far is the MPC860/862 ATM driver on
SourceForge.  Unfortunately this driver was written for the 2.4 kernel,
and does not include MPHY support for ESAR mode.  I have been able to
get this code to compile and run on my kernel, and now I am digging into
the ESAR/MPHY support stuff. =20

I was wondering if anyone else has already done anything along these
lines (either a ESAR/MPHY driver or MPC855 UTOPIA support on the 2.6
kernel), as I would prefer to build on existing code rather than gluing
this stuff together myself.

- Thanks,
  David Pelton.

Hi Dave,

I maintain the mpc860sar project - although it hasn't required much
maintenance for the past year or so.

Nobody has told me about any linux-2.6 port, so it's possible you are
the first to do this.

If you are happy with your port I'd appreciate it if you sent me a
patch which I would then consider adding to the site.

FYI, I also maintain a  PQII driver called mpc8260sar, and I have
been sent a patch which added support for linux-2.6 without breaking
linux-2.4, so I added this to the sourceforge project.  If you like
I'll send you the PQII linux-2.6 patch as a guide for how to do it for
the original PQI driver.

Alex
